I'm finally setting aside some quality time to play this new instrument. I recorded this yesterday: Soundplane into four voices of Aalto via OSC.

It's easier to play Soundplane when you have quantization on. But here I’m playing in its completely fretless mode. Each row of keys is acting as one continuous pitch control, like a violin string. The rows are separated by fourths, giving the whole instrument a range of four and a half octaves.
I'm playing here loosely in Raga Yaman, and going off the rails a time or two. If you want to hear a breathtaking example of what this Raga really sounds like, Google “Ustad Rashid Khan singing Raga Yaman 1988.”
